Baking powder substitutes
Baking powder is a double-acting leavener: it releases carbon dioxide twice — once when wet and once when heated — creating lift in quick breads, cakes, muffins, and pancakes. It contains both an acid (cream of tartar or sodium aluminum sulfate) and a base (baking soda), so it works without any acidic ingredient in the recipe. Substituting it requires either replicating that acid-plus-base reaction or relying on a different lift mechanism, which changes the timing and texture of the result.

| Rank | Substitute | Ratio (replaces 1 cup Baking powder) | Notes |
|---|---|---|---|
| #1 | Baking soda and cream of tartar | Use 1/4 tsp baking soda + 1/2 tsp cream of tartar to replace 1 tsp baking powder | This is the closest functional match — cream of tartar is a dry acid that reacts with baking soda almost identically to commercial baking powder, with no flavor interference. |
| #2 | Baking soda and plain yogurt | Use 1/4 tsp baking soda per 1 tsp baking powder needed; reduce other liquids by 1/2 cup and replace with 1/2 cup full-fat plain yogurt | Works well in muffins and quick breads where some tang is acceptable; yogurt's lactic acid activates the baking soda, but lift is single-acting (starts immediately), so get the batter in the oven without delay. |
| #3 | Baking soda and buttermilk | Use 1/4 tsp baking soda per 1 tsp baking powder needed; replace 1/2 cup liquid in the recipe with 1/2 cup buttermilk | A reliable swap for pancakes and quick breads — buttermilk's acidity activates the soda effectively, though it adds slight tang; batter rises immediately on contact, so don't let it rest. |
| #4 | Baking soda and lemon juice or white vinegar | Use 1/4 tsp baking soda + 1/2 tsp lemon juice or white vinegar to replace 1 tsp baking powder | Works in a pinch but introduces noticeable acidity; lemon juice can mildly affect flavor in delicate cakes, and vinegar can leave a faint aftertaste — better in strongly flavored batters like chocolate cake or banana bread. |
| #5 | Baking soda and plain milk with cream of tartar | Use 1/4 tsp baking soda + 1/2 tsp cream of tartar + substitute 1/2 cup milk for the same volume of any other liquid | A minor extension of rank-1 when you also need to hydrate; the milk adds negligible extra acid but the cream of tartar does the real work — listed separately only because some recipes call for both adjustments simultaneously. |
| #6 | Self-rising flour (partial recipe rework) | Replace 1 cup all-purpose flour + 1 tsp baking powder + 1/4 tsp salt with 1 cup self-rising flour; omit added salt and baking powder | Only viable when the recipe's leavening comes solely from baking powder and the flour quantity is straightforward — works in biscuits and simple cakes, but any recipe with complex ratios or additional leaveners is difficult to rework cleanly; result is noticeably different in texture. |

When to be careful
Recipes that rely on baking powder as the sole structural lift for a very light, neutral crumb — like chiffon cake or white layer cake — are sensitive enough that acid-based substitutes may affect both rise height and flavor noticeably. If the recipe uses a precise ratio of baking powder to flour developed through testing (common in professional pastry recipes), substitution is riskier and results are less predictable.
Why these substitutes work
Baking powder works through an acid-base reaction: sodium bicarbonate (baking soda) reacts with an acid in the presence of moisture and heat to produce carbon dioxide bubbles, which expand in the oven and set into the baked structure. Commercial baking powder is "double-acting" because it contains two acids — one that reacts at room temperature (during mixing) and one that reacts under heat — giving two separate bursts of gas and more reliable rise. Substitutes that pair baking soda with a single acid (yogurt, lemon juice, buttermilk) are single-acting, meaning all gas is produced immediately on mixing, so batters must be baked right away to capture that lift.
The most reliable substitute for baking powder — and the one most consistently recommended by sources like King Arthur Baking and America’s Test Kitchen — is baking soda combined with cream of tartar. It requires no liquid adjustment and produces a nearly identical rise with no flavor difference. If you don’t have cream of tartar, the buttermilk and yogurt options in the table above work well for most everyday quick breads and pancakes, with the trade-off that batter must go into the oven immediately after mixing.
Self-rising flour is included as a last resort, but it requires reworking the recipe and is only practical for simple applications. For anything more precise — layered cakes, chiffon, or recipes with carefully balanced ratios — sourcing actual baking powder before baking is the lower-risk path. Baking powder has a shelf life of roughly 6–12 months; if yours has expired, test it by stirring 1 tsp into 1/2 cup hot water — if it doesn’t bubble actively, it’s spent and a fresh can is the real fix.
Frequently asked questions
- Can I use baking soda alone as a substitute for baking powder?
- Not directly. Baking soda is roughly 3–4 times as strong as baking powder, and it requires an acid in the recipe to activate. Using it alone without adding an acid produces a metallic, soapy taste and uneven rise. Always pair it with an acid (cream of tartar, yogurt, buttermilk, or lemon juice).
- What is the baking soda to baking powder conversion ratio?
- Use 1/4 tsp baking soda to replace 1 tsp baking powder, but only when you also add an acid. Without the acid component, this swap will not work correctly.
- Does substituting baking powder affect flavor?
- It depends on the acid used. Cream of tartar is the most neutral. Buttermilk and yogurt add mild tang that is usually imperceptible in strongly flavored baked goods but can be noticeable in plain white cake or vanilla muffins. Lemon juice and vinegar carry the most flavor risk and are best reserved for recipes with other strong flavors that mask them.
